Hi,
I have found a rather serious set of problems related to homing and gantry squaring issues:
- If the gantry squaring is stopped in any other way than normal script execution, the master/slave axis are left set as U and V.
- If the V axis reaches first the homing limit switch, an error is triggered.
These issues existed, as far as I can tell, since I have first used the MK3 board, but they have bothered me too much now that I have upgraded to the latest version (dated few days ago!).
